YES. YES. YES.

Which components would such a product have (preferably with description, default assignee or CC, and some link to some 'homepage')?

Here's my proposal. If people like it I can create it:

Product: MediaWiki skins

Description: Skins that can be used in MediaWiki. Use to report bugs or visual defects in MediaWiki skins, including built-in skins and those installable via extensions. If an extension contains both a skin and other components, only skin-related defects should be reported in this product.

Components: CologneBlue, MonoBook, Modern, Vector

Default CCes: For all except Vector, it makes sense to keep the existing defaults from the existing "Skin and page rendering" component in MediaWiki. However, for Vector, it has its own component under MediaWiki extensions, so we'd take the CCes and assignees from there.

Basically this, aside from the last bit. If an extension happens to include a skin, relevant bugs should still probably all remain in a single extension component so everything stays together. A separate component should only be created if the extension itself is broken up.

Unless, that is, it's like bluespice and happens to be basically a disaster of extension chunks, but in such cases there's no hope of logical organisation anyway so there's no point worrying about that.

Yeah. This is just an equivalent product to extensions, but for skins, and the current components would be the core skins, with other skins added as people request them, just like with extensions.

Mind, the Vector extension isn't quite the same as the skin, and while it was by the same folks and the skin and extension were eventually merged, I'm not sure the CCs are still applicable anymore. Possibly something to consider, I don't know.

We will also want to move any skins that currently use extension components to use skin components. I only noticed one for Chameleon, but there may be others. (This can be done later, though, I'm sure.)

Sorry, I've been meaning to reply sooner. I agree with everything Tyler and Isarra said.

There are home pages for core skins on mediawiki.org: [[mw:Skin:Vector]] and so on.

Regardless on what you decide about default assignees and CCs, I want to be a default CC on the four components for core skins.

OK, unless Andre objects I'll do it (trying to be more helpful since I only yesterday realized I wasn't on the default CC for the Bugzilla component :P).

...plus move "Chamaleon" to this new "MediaWiki skins" product (from MediaWiki extensions) and its 13 tickets, as mentioned in comment 4.

After doing so, the "Skin and page rendering" component in MediaWiki only refers to issues in MediaWiki core code generically dealing with (any) skin handling, right? I guess I'd need to make this clearer in its component description.

Also, will this mean that somebody (who?) would need to retriage existing tickets in the "Skin and page rendering" component and potentially move skin-specific issues to those new components? 370 open tickets. Urgh. :(

Done. 370 is a lot of tickets, so it will take a while, but I'll work on that.

Uh, thanks. As you've created the new product already there's probably not much left for me to do here. :)

Well I have a bit of free time, and the entire purpose of me getting permissions to change Bugzilla products was to let you not have to do them. :P

What was requested in the summary has been created, hence closing as fixed
